We look at the division of 13516279 by 801 
Let's see how many times 801 fits into 13516279.

Step 1:
801 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 801

Let's proceed to step 2:
13 divided by 801 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 801

Step 3:
When dividing 135 by 801, we get 0 with a remainder of 135.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 135, we get 135.
Grab the next digit (1) from the dividend, add it to 135, then carry on: 1351 / 801

On to step 4:
If we divide 1351 by 801, we get 1 and a remainder of 550.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 550 after subtracting 801 from 1351.
Take the next digit (6) from the dividend and append it to 550, then repeat: 5506 / 801

Moving on to step 5:
801 can be fit into 5506 6 times, resulting in a remainder of 700.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 700 after subtracting 4806 from 5506.
Grab the next digit (2) from the dividend, add it to 700, then carry on: 7002 / 801

Advancing to step 6:
The number 801 fits into 7002 8 times, leaving a remainder of 594.
Record the quotient 8 as the next digit in the result. 
Result so far: 168.0
Deduct 6408 from 7002 and we're left with 594.
Append the next digit (7) from the dividend to 594 and continue with: 5947 / 801

On to step 7:
When dividing 5947 by 801, we get 7 with a remainder of 340.
Record the quotient 7 as the next digit in the result. 
Result so far: 1687.0
The remainder is 340 after subtracting 5607 from 5947.
Take the next digit (9) from the dividend and append it to 340, then repeat: 3409 / 801

Let's proceed to step 8:
3409 divided by 801 is 4 with a remainder of 205.
Record the quotient 4 as the next digit in the result. 
Result so far: 16874.0
Subtract 3204 from 3409 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

On to step 9:
801 goes into 2050 2 times with a remainder of 448.
Write down 2 as next digit of the result. 
Result so far: 16874.2
Subtracting 1602 from 2050 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 10:
801 goes into 4480 5 times with a remainder of 475.
Record the quotient 5 as the next digit in the result. 
Result so far: 16874.25
Subtracting 4005 from 4480 leaves us with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Step 11:
The number 801 fits into 4750 5 times, leaving a remainder of 745.
Put 5 as the next digit of the answer. 
Result so far: 16874.255
If we take 4005 away from 4750, we end up with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Our division results in 16874.255 with a remaining 0.0745.
